I don't know how to do a kernel bisection, it is the first time that I submit a bug. But I have tried 5.3.18 and there aren't any problems, and 5.4.0-050400.201911242031 and output is "dummy".
EDIT: I have installed all the release candidate. v5.4.0-050400rc2.201910062030 works v5.4.0-050400rc3.201910181847 doesn't work tell me if this is enough or if I need to learn how to do a kernel bisection thank you -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1857459 Title: audio doesn't work Status in linux package in Ubuntu: Incomplete Bug description: Kernel: Linux version 5.4.6-050406-generic (kernel@kathleen) (gcc version 9.2.1 20191130 (Ubuntu 9.2.1-21ubuntu1)) #201912211140 SMP Sat Dec 21 11:43:01 UTC 2019 In 5.3.18 audio was ok.
